What Claude said rings alot of truth. I feel we (the cunsumer) has caused this problem. We want everything cheaper, one trip to your electronics superstore will prove that. The products that are still here are the new designs or even prototypes. So

I'm glad to see so much awareness of the challanges the US manufacturing industry is facing. But in problem solving you first have to realize that there is a problem before a solution can be worked out. I firmly believe that if we could convince the

Not sure if you're trying to improve your defect rate (we use dpmo) or your test yield. The question is what do you do if you're happy with your dpmo levels but not some of your first pass yield numbers because certain boards have more parts. Inspe

Machine efficiency is a big one. Placement and auto-insertion machines should have the production rate for a given product recorded in the Routing, Time Standard or Work Instruction. If a given board has a tact time of say 1 minute and you ran 1,000

I am the first to bitch about OEM's. So I will tell you this. I ordered a part from Universal instruments that was made in 1979. They were happy to tell me it was in stock and they would ship it over night. That is the BALLS. not only did they have i

I am not sure about the way the board is made, but I am sure that if you change your handling system to a tray based board handling system you will reduce these problems to a manageable level. Tray carts and trays are clearly the industry standard m

I have a customer with up to 8% scrap from one board supplier and 1% from another supplier for solder dewett and no wet over ENIG finish with mask defined pads. Initially I suspected mask residue on pads because of the no wets but I have come to find

Foam fluxer, ouch!! That hurts. How about this? * Make a sheet metal box to cover your preheaters. [If your boss is really cheap, make a 'box' with 1/2" chicken wire and cover it with aluminum foil.] * Prebake the blank out of the boards, bag the

This sounds like it could be a SIPAD solid solder application. Bring the boards in with the solderpaste already on them in a flattened solid form. Then you could print glue on them without disturbing wet paste. 1.Print glue. (Might take a little

One thing we did for our oven is hook it up to the compressed air system in the factory and bled in a small volume of air to create a positive pressure in the oven. The air is clean (non-oiled) and comes off the dryer. We can attain 5% RH. Remembe
